‘Potter’ trio will finish film cycle

Radcliffe, Grint, Watson ink for two final pics

Daniel Radcliffe, Rupert Grint and Emma Watson will finish out the full term at Hogwarts.

Trio have officially inked deals to reprise their roles in “Harry Potter and the Half-Blood Prince” and “Harry Potter and the Deathly Hallows,” the final two pics in the wizarding franchise based on J.K. Rowling’s best-selling book series.

“It would be inconceivable to imagine anyone else in the roles with which they have become so identified,” said Warner Bros. Pictures prexy of production Jeff Robinov.

Producer David Heyman, who played a key role in bringing author Rowling’s books to the bigscreen and has produced all of the pics thus far, will produce “Half-Blood Prince” and “Deathly Hallows” with David Barron.

Radcliffe, who plays titular character Harry Potter, is in London appearing onstage in Peter Shaffer’s “Equus,” for which he has garnered strong notices.

In recent days, the tabloid press in the U.K. suggested Watson, who plays the role of practical-minded Hermione Granger, might not want to complete the series. Grint plays the role of Harry’s best friend, Ron Weasley.

Warners unspools “Harry Potter and the Order of the Phoenix” — the fifth pic in the series — on July 13.
